tight fitting cloth work gloves that don’t obstruct writing
Pocket knife. Clip one in your pocket for a week and you will be amazed how much you use it. I always have a cheap Gerber or nice Kershaw on me.
Yep. Depending on if I’m going into the office or staying home, I have two Victorinox pocket knives of which I always carry one. Slicing apples, cleaning dirty nails, (un)screwing stuff, prying out a battery, cutting open packages, uncapping a bottle. All from a package-of-gum sized aluminium tool in my pocket
My planner. My whole life is there.
Do you have a specific planner that you prefer?
iPhone.

Oh, my Leatherman (Skeletool/Wave, depending on the day).
